The U.S. Geological Survey (USGS), which began using aerial photographs for mapping in the 1930's, archives photographs from its mapping projects and from those of some other Federal agencies. In addition, many images from such space programs as Landsat, begun in 1972, are held by the USGS.
Black-and-white, natural color, and color infrared aerial photographs over the United States are available in a digital format at a resolution of 400 or 1,000 dpi. (1937 - 2014)
John Walter's site allows viewing Earth from various perspectives. Lunar views include the ability to make custom images and a perigee and Apogee calculator.
A variety of solar system objects available for viewing include Mercury, Venus, Mars and its moons.
The USGS EROS Center operates the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.
The goal of the Mars Exploration Program is to explore Mars and to provide a continuous flow of scientific information and discovery through a carefully selected series of robotic orbiters, landers and mobile laboratories interconnected by a high-bandwidth Mars/Earth communications network.
This collaborative service is designed to provide easy access to the publicly released images from various Solar System exploration programs. New images are added regularly.
TerraFly utilizes satellite imagery and aerial photography to allow users to virtually “fly” over the continental United States. The application is designed to aid in the dissemination and visualization of geospatial data via the Internet. (“A public service of Florida International University sponsored by the National Science Foundation, NASA, the United States Geological Survey, and IBM.”)
